Technical Field
The present invention relates generally to communication connectors such as RJ45 type plug connectors, and in particular to high speed RJ45 connectors that use Plug Interface Contact (PIC) covers to switch the paths of 3-6 split pairs.
Background
RJ45 jack crosstalk compensation can be generally simplified by: reducing the amount of crosstalk added by the plug interface contacts of the jack and shortening the compensation distance from the plug/jack contact points (the approximate location of the crosstalk sources in the mating plug and jack). The compensation distance is shortened, the crosstalk of the plug and jack interface contacts is reduced, the compensation is placed at the interface on the non-current bearing post, the phase delay between the plug/jack contact point and the jack crosstalk compensation network is reduced, the crosstalk compensation amount is reduced, and the compensation for the jack crosstalk is simplified.
SUMMERY OF THE UTILITY MODEL
In one embodiment, a high speed RJ45 connector has a housing with an opening. The housing contains a carriage assembly. The carriage assembly has a plurality of plug interface contacts with a Plug Interface Contact (PIC) cover at least partially surrounding the first plug interface contact. The PIC cover is electrically insulated from the first plug interface contact and is electrically connected to the second plug interface contact.
In one embodiment, the second PIC cover at least partially surrounds the third plug interface contact. The second PIC cover is electrically insulated from the third plug interface contact and is electrically connected to the fourth plug interface contact.

Detailed Description
The utility model relates to a RJ45 network socket. The Plug Interface Contact (PIC) interface for contacts 3 and 6 is formed using a thin layer of contact material that is electrically insulative and wrapped around electrically conductive mechanical spring contacts connected to contacts 6 and 3, respectively. The spring contact support at PIC position 3 is electrically connected to PIC interface 6, while the spring contact support at position 6 is electrically connected to PIC interface 3. The PIC interface connection with the spring contact is made so that it does not interfere with the plug mating. The reduced PIC interface thickness at locations 3 and 6 reduces 2-3, 3-4, 5-6, and 6-7 crosstalk. The supports of PIC locations 3 and 6, which have been connected to locations 6 and 3, respectively, provide crosstalk compensation 2-6, 4-6, 3-5, and 3-7 near the plug/jack mating interface.
